Are you sure, that BufferedReader-implementing classes you use are
serializable or network-aware?

Subject: [jBoss-User] Send BufferedReader from JSP up to JBoss fails.
Hello you wise people of the JBoss community.
Since i'm unable to search for information on-line at jboss.org, and no
similar informations is present in my local JBoss mailling-list archive, i
will try this forum.
I have a upload page (JSP). In this upload page i grab the stream with all
the good information from the user.
On my JSP page i find all the "other" input information such as user-id and
password etc.
Finally there is a file, and i would like to parse the rest of the file on
to my JBoss beans where all my logic is located.
I would like to handle the input similary whether it comes from a
upload-form or from a local file - or something different.
I read the input one line at a time, and would like to use the
StreamTokenize on it because it can handle Strings and numbers quite
excellent.
My Session stateful bean got a function :
public int prepareUploadItems (BufferedReader r) throws RemoteException,
CreateException;
My bean got a function :
public int prepareUploadItems (BufferedReader r)
that only calls the above function.
I traced the error to the function calling the JBoss function:
return m_upload.prepareUploadItems (r);
The JBoss function will not start (got a System.out.println as the first
line).
The error present it-self in my browser !
This is the Explorer error :
Error: 500

Can JBoss not get a handle to a stream from JSP ?
Any help would be appreciated !
